ARRANGEMENT 0F TRACK FOR RAILWAY-GUNS.

Specification of Letters Patent.

Patented Dec. 7, 1920.

Application filed September 4, 1920. Serial No. 408,401.

T 0 all whom it may concern:

Be it known that I, RUooLr HARTWIG, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Arrangement of Track for Railway-Guns, of which the following is a specification.

This invention relates to that typeof arrangement of railway track for railway guns, which enables the traverse to be taken by running the gun over the track. The object of the invention is to provide an arrangement of railway track of this kind, which affords a field of traverse up to 360, while at the same time it takes up but little space and guarantees great stability of the gun when it is fired.

The invention will be described with reference to the accompanying drawings which diagrammatically illustrate the invention.

Figures 1 and 2 show a plan view of a construction of the arrangement of railway track together with the gun in different positions and Figs. 3 and 4 are similar views of a second construction of the invention.

Referring to Figs. 1 and 2 the arran ement of railway track is in the form 0 a junction, the two sections of rails of which are denoted by A and A which sections are connected with the track A which leads to the junction by a set of points, a turntable or the like. The gun, which is intended to be used on this junction is provided with a railway gun carriage, the frame B of which carries the gun barrel B and is supported on two bogies B B When running the gun into the junction the rear bogie B for example, is first run onto the track A and then the front bogie B is run on to the track A, which causes a mutual rocking of the frame B and of the bogies B B about the axes 6* 5 By running the bogies on to the tracks A and A the gun can be brought from the position shown in dotted lines in Fig. 1 through the positions indicated by dot and dash lines into the position indicated by full lines in Fig. 1. In all the intermediate positions the barrel B of the I track A, the gun barrel gun points toward the left in an upward direction in the drawings. Fig. 2 shows how the gun barrel B is pointed toward the right in an upward direction when the 'bogies B B are in a different mutual position on the tracksA and A If on the contrary the front bogie B be run on to the track A and the rear bogie B on to the B will point downward (in the drawings).

By running the gun around the junction therefore, a field of traverse up to 360 can be obtained, as a rule however only a comparatively small angle of this field of traverse will be made use of. The junction is so laid out that the firing positions'likely to be required are situated in the vicinity of the reversed position of the gun. This insures the advantage that at least one of the bogies describes a comparatively large angle with the directionof fire (see the reversed position indicated by full lines in Figs. 1 and 2, in which the bogie B is at right angles to the direction of fire and the bogie B likewise at a comparatively large angle thereto). In consequence of this the railway gun carriage does not run back when the gun is fired, so that it is not necessary to run the gun out into the firing position again after each shot. The above described arrangement of track is further distinguished by the fact that it takes up far less space than the sections of railway with large radii of curvature hitherto used for the same purpose and in which the bogies of the gun run on one and the same line of rails.

The arrangement of track shown in Figs. 3 and 4 is constructed as a triangular junction with three sides C. C C and approach lines C C The parts of the gun concerned are denoted as in Fig. 1 by B, B B B The method of using this arrangement of railway track can be clearly understood with reference to the drawings and therefore needs no further description.
